St tes Pw I 2,718,413 r BASE FOR COPYING INLOOSE LEAF BOOKS Georg Leonard Fransson and Gustav Ake Lennart Winqvist,Stockholm, Sweden, assignors to Aktiebolaget Galco, Stockholm, Sweden, acorporation of Sweden Application May 27, 1952, SerialNo. 298,228 r 3Claims. (Cl. 282-8) The present invention refers to a base for journalleaves and the like, on which handwriting is to be copied with the aidof carbon paper or the like, said handwriting being executed on accountleaves or the like attached in a loose leaf book by means of attachingprongs or the like.

The principal object of the invention is to provide an improvedsupport-for the account leaves thereby enabling one to do the requiredcopying in a considerably simplified and more concise manner. Morespecifically, the improved support is characterized by a lower baseplate adapted to be attached along one edge to the prongs of the book,and an upper writing plate hinged to the opposite edge of the base plateso that by swinging the writing plate upwardly about its hinge axis eachof a plurality of account leaves initially placed between the plates maybe brought in succession onto the upper side of the writing plate forcopying.

This and further objects and advantages of our invention will beapparent from the following description and accompanying drawing, ofwhich:

Fig. 1 shows the base in a plan view, and Fig. 2 shows a section on line11-11 in Fig. 1. Fig. 3 shows the base as arranged in a loose leaf book,this figure representing a cross section through the book and the base.Fig. 4 shows a detail.

In the drawing, 1 designates a plate, the attaching or base plate, whichis made from aluminum, masonite, plastic or the like, for example, saidplate being provided at one edge thereof with hooks 2, which arepreferably made integral with the plate and of such configuration as topermit of being hooked on the prongs 3 for the paper leaves provided inthe loose leaf book (Fig. 3). The outer portion of the plate 1 with thehooks 2 is preferably bent downwardly, so that the plate is made toagree with the curvature assumed by the underlying paper leaves 4 whenthe cover is open (see Fig. 3

At the edge of the attaching plate 1 opposed to the hooks 2, a writingplate 5 substantially coextensive in area with base plate 1 and theleaves to be copied is mounted by a hinge connection so as to beswingable about the hinge axis and displaceable in the longitudinaldirection of said axis, said writing plate 5 consisting likewise of astiff material, such as aluminium, preferably with a special surfacecoating, such as a thin covering of masonite, plastic or the like on theupper side and preferably also on the lower side thereof. If desired,the plate may consist of such materials in its entirety.

In the example of embodiment shown, the attaching plate 1 has arrangedthereon a channel-shaped guide 6 serving for the mounting of the plate 5and having an inner surface curved on a circular are, said guide havinga runner 7 displaceably and rotatably arranged therein, which runner isrigidly connected with the writing plate 5. The runner 7 and plate 5 areso disposed that plate 5, when in a position parallel to plate 1, willbe a short distance from the latter.

The writing plate 5 is of such a width that the edge 5' thereof opposedto the mounting edge extends beyond the side notches 2' of the attachingplate. Preferably, the outeredge portion'of the'writing plate 5 is alsobent downwardly in the same manner as the outer edge of the plate 1. Y 7

Mounted on hinges 8 at the mounting edge of the writing plate 5 is a bar9 adapted to be swung up against spring action, said bar having edgerecesses 11 corresponding to pins 10 secured inthe plate. The pins 10enter corresponding holes in the journal leaf 12 '(Fig.

3), on which hand-writing executed on an account leaf 13 attached in theloose leaf book is tobecopied. The requisite carbon paper may also besecured on these pins. A finger grip for the operation of the bar 9is'denoted by 14. f I I For'the retainment of the carbon paper resilientclamps configuration of these clamps" appearing I more clearly from Fig.4. The clamps consist of a plate 16 of spring steel, which is formed atone end thereof into a finger grip 16 while being provided at the otherend thereof with two tips 17, 18 separated by a slit. Thetip 17 isprovided with'holes 19 for pins, by'means of'which the clamp is securedto the plate 5. This tip 17 is by a downward bend 20 disposed at a lowerlevel than the finger grip portion 16'. By the resiliency of the bend 20the other tip 18 is pressed downwardly to bear resiliently on thewriting plate. If the grip member 16' is pressed in the direction of thearrow p, the tip 18 will be swung upwardly, so that the edge of thecarbon paper can be moved underneath the same. The two spring clampsshown in Fig. 1 are disposed so as to permit of being readilymanipulated with one hand, while the edge of the carbon paper is movedin underneath the tip 18 with the other hand.

By the provision of the writing plate 5, the work in writing will beconsiderably simplified. Account leaves pertaining to a section laidopen in the loose leaf book, and which have not yet been provided withnotations, may lie underneath the writing plate, until it is their turnto be written on. For this reason, only one account leaf in addition tothe journal leaf secured on the writing plate need be present on thelatter in working. When the notation is finished on an account leaf, thelatter is turned in the ordinary manner to the left in the book, thenext account leaf, arranged in a stepwise fashion underneath the formerone, being then brought up onto the writing plate.

When a plurality of account leaves are present in a section laid open inthe loose leaf book between the attaching plate 1 and the writing plate5, if the edge 5' of the latter did not reach the prongs 3, this edgewould move laterally with regard to the attaching plate 1 as the numberof account leaves diminished during the progress of the notations. Adisplacement of the account leaves brought into writing position wouldthen take place successively relatively to the journal leaf secured onthe writing plate, so that the notations copied on the latter would notcome exactly into the vertical columns of the journal leaf. Thus theposition of the notations in the transverse direction of the book wouldbe displaced in dependence on the number of leaves between the plates 1and 5.

To avoid this disadvantage occurring in connection with a great numberof account leaves or the like, the edge 5' of the writing plate is inthe example of embodiment shown extended to cover those portions 2' ofthe hooks of the attaching plate 1 which embrace the prongs 3. As willbe seen from Figs. 2 and 3, the outer edge 5' of writing plate 5 bearson the prongs 3 above and at some distance from the point of attachmentof the attaching plate Patented Sept, 1955 1. The number of accountleaves between plates 1 and 5 mustnot'be so great as to" raisethe outeredge'ef plate 5 from the prongs. Should this number be slightlyexceeded, the writing plate 5 may be made sufiiciently flexibleforthefree outer ed es to be pressed intoc'ontactj with the prongs 3.

'The' account leaf 13, Fig. ?,in consideration for writingv may now be.brought close up to the writing plate, and

its position relatively to the writing plate will then always be exactlythe same, independently of the number of account leaves 13 enclosedbetween the plates 1 and 5. The notations on the various account leaveswill then al' walys be copied in an exact position relatively to the'vertical columns of the journal leaf.

Whatwe claim. is y 1 ha support for journal leaves on which to copy withthe aid of carbon paper or the like handwritten en-.

tries on account leaves attached in aloose leaf book by means of prongs,the combination comprising a base plate havinga plurality of hook-shapedprojections along one edge thereof establishing notches adapted to behooked ontothe prongs of said loose leaf book, a writing plate hingedlyconnected along one edge to the opposite edge of said base plate so thata plurality of account leaves initially. placed between said plates maybebrought insuccession onto the upper side of said writing plate, the.

edge of said writing plate opposite the hinged edge thereof rneanscarried by said Writing plate adjacent the hingedplaceable along itsaxisin said guide, and said guide being adapted to serve as a foot for thesupport contacting the surface on which the book is placed for copying.

3. A support for journal leaves as defined in claim 1 and which furtherincludes spring leaf clamps carried by said writing plate forclampingcarbon paper in place between said account and journal leaves.
